If you are not familiar with the term API, then you must know that API refers to Application Programming Interface which basically is a software intermediary. API allows two applications to communicate with each other. Whenever you scroll a social media app like Instagram, Facebook, send a text message, or check the weather on your phone, there is an API at play.
Whenever you use an application on any of your cellular devices, the application establishes a connection with the Internet and transmits data to a server. The server then further retrieves that data, decodes it, runs it thoroughly and transmits it back to your cellular device. The application then receives the data and then interprets that data and then provides the user with the information required in a readable way.
To make things more simple, imagine yourself sitting at a restaurant with a menu in your hand. This goes without saying that every restaurant has a kitchen. The kitchen here symbolizes a "system" which is responsible for preparing your order. The only thing which is missing here is the link required to communicate your order to people working in kitchens and then deliver your food to you right at your table. The waiter responsible for conveying your order to kitchen authorities and then bringing the order back to your table plays the role of API. The waiter plays the role of messenger, and this is exactly what the API does.
At one point or another, you may have come across the process of searching and booking flights online. Similar to the restaurant, while choosing flights, you are presented with a variety of options to choose from. This includes the option of different cities, departure and return dates, and much more. Imagine yourself booking a flight on any airline website. You will select a departure city and date, a return city and date, travelling class, as well as other variables. When you proceed to book your flight, you usually interact with the airline’s website to access their database. This way, you are actually able to see if any seats are available on those dates and what might be the fare.
The purpose of the API is to provide an added layer of security. With an API, data on your cellular device is never fully exposed to the server. Simultaneously, the server is never fully exposed to a user's phone. To make things work, each communicates by utilizing small packets of data, and share only what is necessary. For instance, if you intend to order food at a restaurant, you will simply inform the restaurant about your desired meal, this will be followed by them telling you what they need in return, and in the end, both the end user and restaurant gets what they want.

From here on, Click on the Generate Token button for the Instagram Tester user of your app. However, it is important to note that Tokens can only be generated for public Instagram accounts.
Final Words: Modern APIs have some characteristics which the previous versions did not. For instance, they strictly abide by standards which are developer-friendly, easily accessible and understood broadly. Aside from this, they are way more standardized with added layers of security.
